#dodecahedrons — Public Fediverse posts

The latest article in my Staring into Space project is on Gallo-Roman #dodecahedrons, a strange #artifact found in northwestern Europe between about 200-400 CE. Not likely to have much to do with astronomy, but definitely an intriguing rabbit hole to chase down. https://www.wasteflake.com/tiki-read_article.php?articleId=45

These #Roman #dodecahedrons, made of a copper alloy, dating to the 3rd century CE, are pretty interesting. Apparently, nobody knows what they're for, and more than 100 have been discovered in various Roman sites. While not standardized, they're all roughly the size of a grapefruit. #Archeologists suspect they're #religiousArtifacts given the prevalence of superstition, but I think they're used to play a game. Something like #bocce, maybe. What do you think?

You might find this picture somewhat interesting, I call it “Cairo Transitions”, and it is from about 4 years ago.

It shows a square grid being transformed into a #CairoTiling by emphasizing different edges in a 3D “bent #pentagon” tiling.

The underlying pattern was created based on the fact that #cubes fit nicely into #dodecahedrons (as mentioned by @johncarlosbaez in this recent post https://mathstodon.xyz/@johncarlosbaez/109290809194904775).

There is a chance that you might have seen it at JMM2020.

Another iteration.

Here is something pretty from 4 years ago.

One iteration of a ring of 5 edge-connected #dodecahedrons forming the "#pentagon" used to make up another "#dodecahedron"

Some #dodecahedrons attached at edges. Never mind the extra bits used for construction 😊.

This is a link to a Twitter Moment that I set up 4 years ago about my investigations related to “The Creature” (which itself came into being more than 3 decades ago).
